If anyone is interested I have created the POI points of interest files for the GARMIN GPS unit. I have included Flying J, Petro, Pilot and TA.
You will need the Garmin POI loader from the Garmin website to install these CSV comma separated files.
Once installed it will show up in your POI Points of Interest menu item. It will allow you to seach all at once with the closest first or by truckstop as in Petro, Flying J, Pilot or TA.
I don't have an FTP site anymore so if someone would email me at [email protected] I'll email them back so you can post a link to them
When saving the files on your hard drive make sure you save them as Pilot, Petro, Flying J and TA as this filename will be the one that shows up on the category when you load them.
